RELATED APPLICATIONS

This application claims priority of U.S. application Ser. No. 62/002,727, filed on May 23, 2014, titled INTERNAL SUPPORTS FOR INFLATABLE STRUCTURES, which application is incorporated in its entirety by reference in this application.

BACKGROUND INFORMATION

1. Field of Invention

The present disclosure relates to inflatable products and, in particular, to an inflatable product incorporating a durable tensioning structure that is light in weight and low in cost.

2. Background

Inflatable products such as inflatable toy structures, inflatable beds, inflatable sofas, inflatable pools and the like are well known in the art. Such products are typically light in weight, easy to pack and store, and easy to carry.

Most inflatable products utilize internal structures in order to form the product into its intended, predetermined shape upon inflation. For example, air beds may incorporate one or more coil-beams or I-beams within the inflatable cavity of the bed. These beams are generally disposed at various locations within the inflatable cavity to shape the bed as the inflatable cavity is pressurized. The beams prevent the air bed from expanding evenly on all sides, similar to that of a balloon. More particularly, in order to maintain the generally rectangular shape of the air bed, these beams may join, for example, upper and lower surfaces of the air bed to one another to restrict their separation during inflation.

The number and spacing of the beams is proportional to the sharpness of the rectangularity of the inflated product. In other words, the greater the number and/or linear extent of the beams within the inflatable cavity, the “flatter” the bed surfaces become.

In conventional inflatable products, such as the air beds described above, the beam structures are typically made of plastic or PVC sheets with a sufficient thickness to ensure that external loads are spread and concomitant tensile stresses are reduced in the product material. As such, conventional inflatable structures utilizing plastic beam structures may meet their desired load requirements by varying the thickness of the beams. This contributes to increased weight of the inflatable product. Similarly, an increase in the thickness and/or spatial density of the beams also increases the compressed/folded volume of the deflated inflatable structure.

Beam structures made of a solid PVC sheet generally are not strong enough to withstand high pressure loads generated during inflation. Such structures are easily deformed once stretched beyond their elastic limit. This contorts the shape and weakens the strength of the inflatable structure. Further, such beam structures may also rip or tear along seams coupling the beam structures to, for example, the upper and lower surfaces of the inflatable structure if the inflatable structure is over-inflated.

Accordingly, a need therefore exists for a tensioning structure suited for inflatable products that is durable, yet lightweight and easy to manufacture.

SUMMARY

A tensioning structure for use in an inflatable product is provided. In one example, the inflatable product includes a first sheet, a second sheet disposed opposite the first sheet, where the first sheet and second sheet are spaced apart to define a gap therebetween, and where at least one tensioning structure spans the gap between the first sheet and the second sheet. The tensioning structure may include a panel made of a single sheet of porous material, where the panel includes a first end and an opposing second end. The tensioning structure may further include a first coupling affixed to the first end of the panel, where the first coupling is also coupled to the first sheet, and a second coupling affixed to the second end of the panel, where the second coupling is also coupled to the second sheet.

The panel may be made of material having an open cell mesh construction. In one implementation, the open cell mesh construction comprises an array of evenly spaced, hexagon-shaped apertures. In another implementation, the open cell mesh construction comprises an array of evenly spaced, circular-shaped apertures.

The first weld sheet and the second weld sheet may each include a first strip of material affixed to a front surface of the panel and a second strip of material affixed to a back surface of the panel. In other implementations, the first weld sheet and the second weld sheet may each include a single strip of material folded about the ends of the panel such that one end of the strip of material is affixed to a front surface of the panel and the opposite end of the strip of material is affixed to a back surface of the panel. In yet another implementation, the first end of the panel and the second end of the panel may be coated with PVC or other durable material having favorable bonding characteristics to form coating layers that are coupled to the first sheet and the second sheet.

In a second example, the inflatable product may include a first plastic sheet, a second plastic sheet spaced apart from the first plastic sheet, an inflatable air chamber defined by the first plastic sheet and the second plastic sheet, and a plurality of tensioning structures disposed within the air chamber, where each tensioning structure is coupled between the first wall and the second wall. Each of the plurality of tensioning structures may include a panel made of a single sheet of porous material, a first weld sheet affixed to a first end of the panel and affixed to the first plastic sheet, and a second weld sheet affixed to a second end of the panel opposite the first weld sheet and affixed to the second plastic sheet.

In a third example, the inflatable product may include a first wall, a second wall spaced apart from the first wall, an inflatable air chamber defined by the first wall and second wall, and a plurality of tensioning structures disposed within the air chamber, where each tensioning structure is coupled between the first wall and the second wall. Each of the plurality of tensioning structures may include a panels made of single sheet of porous material, a first weld sheet affixed to a first end of the panel and affixed to the first sheet, and a second weld sheet affixed to a second end of the panel opposite the first weld sheet and affixed to the second sheet.

A method for producing an inflatable product is further provided. The method includes the steps of providing a first sheet made of weldable material, and providing a second sheet made of weldable material, where the first sheet is spaced apart from the first sheet to define a gap therebetween. The method further includes the step of providing at least one tensioning structure spanning the gap between the first sheet and the second sheet, where the at least one tensioning structure includes a tensile sheet made of porous material. The tensile sheet includes a first end and an opposing second end. A first weld strip is applied along the first end of the tensile sheet and a second weld strip is applied along the second end of the tensile sheet, where the first weld sheet is coupled to the first sheet and the second weld sheet is coupled to the second sheet.

In one implementation, the inflatable product is an air mattress having an upper sheet, a lower sheet, and a side wall. In the implementation, the method further comprises the steps of creating an inflatable chamber defined by the upper sheet, the lower sheet, and the side wall by coupling the side wall to the upper sheet and coupling the side wall to the lower sheet; and providing a valve in communication with the inflatable chamber to facilitate inflation and deflation of the air mattress.

In another implementation, the inflatable product is an inflatable spa having an inner wall, an outer wall, a top wall, and a bottom wall. In this implementation, the method further includes the steps of creating an inflatable chamber defined by the inner wall, the outer wall, the top wall, and the bottom wall by coupling the inner wall, the top wall, and the bottom wall, and coupling the outer wall to the top wall and the bottom wall; and providing a valve in communication with the inflatable chamber to facilitate inflation and deflation of the inflatable spa.

DETAILED DESCRIPTION

FIGS. 1-9 illustrate examples of different implementations of tensioning structures 100 employed in inflatable objects. The tensioning structures give shape to inflatable objects, such as inflatable couches, beds, waterslides, structures, or swimming pools. The tensioning structures are lightweight and occupy minimal volume when the inflatable objects are deflated and packed away, while also functioning as strong and durable internal supports upon inflation and use of the inflatable object.

An exemplary tensioning structure in accordance with the present disclosure utilizes thin, flexible I-beam structures that join two areas of fabric to one another. The I-beam structures comprise open cell or mesh material and are firmly connected at their ends to adjacent fabric by an intermediate material, such as a strip of plastic. The intermediate material is in turn firmly attached to the fabric. The area of contact between the intermediate material and the I-beam structure may be adjusted to impart a connection strength commensurate with the tensile strength of the I-beam structure. Similarly, the area of contact between the intermediate material and the adjacent fabric may also be manipulated to impart a fabric/tensioning structure connection strength commensurate with the aggregate tensile strength of all of the I-beams comprising the inflatable object.

Various tensioning structures are described in detail below. It is contemplated that any of the tensioning structures described herein may be used in any inflatable product, either alone, as a group, or in combination with one another as required or desired for a particular design. In addition, it is contemplated that tensioning structures in accordance with the present disclosure can be used in other contexts, such as in camping, recreational, entertainment, amusement, extreme sports, fall-arrest safety and fire rescue equipment, or in any other context where a lightweight, inflatable structure is needed.

In one exemplary application shown in FIGS. 1-5B, the tensioning structures 100 may include one or more I-beam support structures 102 incorporated into an inflatable product, such as an inflatable air mattress 104. The air mattress 104 may include a top sheet 106, a ground-contacting bottom sheet 108, and a flexible sidewall 110. The flexible sidewall 110 may be fixedly connected or welded to the peripheries of the top sheet 106 and the bottom sheet 108 to form an inflatable chamber 112. Within the inflatable chamber 112, the I-beam structures 102 may be attached to inner surfaces of the top sheet 106 and bottom sheet 108. The I-beam structures 102, collectively, form channels that help shape and structurally reinforce the inflatable chamber 112.

The top sheet 106, bottom sheet 108, and sidewall 110 may be constructed of plastic, polyvinyl chloride (PVC), thermoplastic rubber (TPR), polyethylene vinyl acetate (PEVA), ethylene vinyl acetate (EVA), thermoplastic polyurethane elastomer (TPU), neoprene-coated fabric, or any other suitable material. In some implementations, the top sheet 106 may be overlaid with a layer of fabric, padding, flocking, or other material to provide a sleeping surface for the user. One or more air valves (not shown) may be provided and coupled, for example, to the sidewall 110 for inflating and deflating the inflatable chamber 112.

Although air mattress 104 is shown as a single layer, the present disclosure may also apply to mattresses having multiple layers (e.g., double layers). In addition to mattresses, tensioning structures of the present disclosure may be used in other inflatable products such as inflatable boats, inflatable islands, floatation devices, swimming pools, inflatable slides, and any other inflatable devices.

FIG. 2 is a front view of the I-beam structure 102. The I-beam structure 102 may be generally rectangular in shape and include a panel 202 made of a material having fibers that form an open cell mesh construction where the cells may be shaped, cut, or otherwise formed into various geometrical shapes. The I-beam structure 102 acts as a retention member, and functions to limit the outward expansion of the top and bottom sheets 106 and 108 (for example, into a balloon shape) when the mattress 104 is filled with air. This type of retention is well known to those skilled in the art of inflatable devices, such as floating devices, air mattresses, and the like. Accordingly, although I-beam retention members are shown herein, other retention members can be used in accordance with the present disclosure, including tufted beam structures, coil-beam structures, X-beam structures, and the like. It is noted that, regardless of the type of retention structure used, the shape and comfort of the inflatable chamber will be directly dependent upon the number of retention structures used therein.

As illustrated in FIG. 3, the panel 202 may comprise a circular mesh array 302. The mesh array 302 may be formed from a plurality of fibers 304 that define a plurality of pores or apertures 306 therebetween. While the apertures 306 are illustrated in FIG. 3 as being circular in shape, in other implementations, the fibers 304 may define a plurality of apertures 306 having other geometric shapes, for example, hexagonal or triangular-shaped apertures 306. When the mattress 104 (FIG. 1) is inflated, thereby engaging one or more of the I-beam structures 102, the fibers 304 may be placed in tension to maintain the shape and prevent over-expansion or “ballooning” of the mattress 104.

The fibers 304 may be bundled or arranged in a staggered grid pattern to form a lattice of evenly spaced, circular-shaped apertures 306. The apertures 306 may be spaced apart and arranged at regular intervals to provide the panel 202 (FIG. 2) with a substantially constant tensile strength.

Referring now to FIG. 4A, the panel 202 may comprise a skeletal hexagonal cellular mesh array 402. The mesh array 402 may be formed from a plurality of fibers 404 that define a plurality of pores or apertures 406 therebetween.

The mesh array 402 may include a first set of spaced-apart and parallel fiber members 408, a second set of spaced-apart and parallel fiber members 410, and a third set of spaced-apart and parallel fiber members 412. The first, second and third set of fiber members 408, 410, and 412 intersect each other in transverse relation such that, together, they form a plurality of hexagon-shaped apertures 406.

The fibers 404 may be bundled or arranged in a staggered grid pattern to form a lattice of, evenly spaced, hexagon-shaped apertures 406. The fiber members 408, 410, and 412 may be spaced apart at regular intervals to provide the panel 202 (FIG. 2) with a substantially constant tensile strength.

In some implementations, as shown in FIGS. 3 and 4A, the fibers 304, 404 may comprise a cloth or cast screen or mesh of fabric such as cloth, nylon, polyester or other durable material. In other implementations, fiber bundles 414 may be constructed by knotting or weaving together strands of materials such as twine, wire, string, or threads.

In another example, as shown in FIG. 4B, the panel 202 may be formed from a plurality of ligaments or frame members 420 that define a plurality of pores or open cells 422 therebetween. The frame members 420 may be arranged in a grid pattern, including a first set of spaced-apart and parallel frame members 424 and a second set of spaced-apart and parallel frame members 426. In this grid pattern, the first set of frame members 424 is transverse to the second set of frame members 426 such that the first set of frame members 424 intersects the second set of frame members 426 at a junction 428. In example shown in FIG. 4A, the first set of frame members 424 intersects the second set of frame members 426 to form a lattice of, evenly spaced, diamond-shaped open cells 422. Adjacent frame members 420 may be spaced apart at regular intervals to provide the panel 202 with a substantially constant tensile strength. The size and shape of each open cell 422 may vary depending on the thickness and orientation of the surrounding frame members 424, 426.

In some implementations, the frame members 420 may comprise a cloth or cast screen or mesh of fabric such as nylon, polyester or other durable material. In other implementations, frame members 420 may be constructed by knotting or weaving together strands of materials such as twine, wire, string, or threads.

Turning back to FIG. 2, each I-beam structure 102 may include weld strips 204 and 206 connected to upper and lower ends of the panel 202. The upper and lower weld strips 204 and 206 are in turn welded to the top sheet 106 and bottom sheet 108, respectively, such that forces urging the top sheet 106 and bottom sheet 108 apart are encountered by tension in the open cell structure of the panel 202.

FIG. 5A is a cross section of the I-beam structure 102 taken along line 2-2 of FIG. 2. As shown, and briefly described above, the structure 102 may be manufactured as a dual layer structure using a pair of weld strips 204 and 206, both above and below the panel 202. The weld strips 204 and 206 may comprise relatively thin strips of plastic, PVC, or other durable material. For example, the weld strips 204 and 206 may be constructed to a thickness of 0.20 mm-0.40 mm and a width of 20 mm-40 mm; however, the dimensions of the weld strips may vary depending on the size and inflation pressure of the inflatable product.

The use of two mutually opposed weld strips 204 and 206 employs a gripping action to “sandwich” the panel 202 therebetween, thereby contributing to a high-strength coupling interface. The weld strips 204 and 206 may be affixed to the panel 202 using suitable coupling techniques, such as radio-frequency (RF) welding, hot-air coupling (e.g., melting or welding), adhering (e.g., gluing) or other means known in the art. When implemented in an inflatable product, the resulting dual-layer tensioning structure 100 has improved strength and can be welded to the top sheet 106 and bottom sheet 108, on either side (see e.g., FIG. 6B).

In other implementations, as shown in FIG. 5B, a single weld strip 502 may be used and folded about the lateral ends of the panel 202 such that one end of the weld strip is affixed to a bottom surface of the panel 202 and the opposite end of the strip is affixed to a top surface of the panel 202. In another implementation, one end of the weld strip 502 may be affixed to a surface of the panel 202, while an opposing end the weld strip 502 may be coupled to a corresponding top sheet 106 or bottom sheet 108. In yet another implementation, the end regions covered by welds strips 204 and 206 in FIG. 2 may, alternatively, be coated by a plastic or PVC coating or coating of another suitable material, thus forming coating layers that may be welded to the top sheet 106 and bottom sheet 108, respectively.

FIG. 6A is a perspective view showing a second example of an implementation of the present disclosure where the tensioning structures includes a number of I-beam structures 602 used in an inflatable structure such as an air mattress 600. The mattress 600 includes a sleeping surface at top sheet 604, and a ground-contacting bottom sheet 606. The mattress 600 further includes a sidewall 608 that is fixedly connected or welded to the peripheries of the top sheet 604 and the bottom sheet 606 to form an inflatable chamber 610. In this example, the I-beam structures 602 may include an open cell mesh fabric 612 having one or more cut-outs 614 such that air may flow past the ends of structures 602.

FIG. 6B is a cross-sectional view of the air mattress 600 of FIG. 6A. As shown, weld strips 616 and 617 affixed along the lateral ends of the mesh fabric 612 are bent to a substantially 90° angle at opposite ends of the fabric 612, such that each lateral end of the I-beam structure 602 may be coupled between the top sheet 604 and the bottom sheet 606 of the air mattress 600 by, for example, sewing, stitching, RF welding, hot-air coupling, adhering, or other means known in the art. Because each I-beam structure 602 is air permeable, due to the open cell structure of the mesh fabric 612, pressurized air flowing into the inflatable chamber 610 is permitted to freely flow from one portion of the chamber to an adjoining portion of the chamber during inflation or deflation, as illustrated by arrows 618 and 620. Further, the open cell structure of the mesh fabric 612 provides tension for maintaining the shape of the air mattress 600 as internal pressure increases, thereby preventing the air mattress 600 from expanding evenly on all sides, similar to a balloon.

FIG. 7A is perspective view showing a third example of an implementation of the present disclosure where the tensioning structures includes a plurality of coil-beam structures 702 used in an inflatable structure such as an air mattress 700. In this example, the mattress 700 includes a top sheet 704 and a bottom sheet 706. The mattress 700 further includes a sidewall 708 that is fixedly connected or welded to the peripheries of the top sheet 704 and bottom sheet 706 to form an inflatable chamber 710. The coil-beam structures 702 may comprise an open cell mesh fabric 712.

FIG. 7B is a cross-sectional view of the air mattress 700 of FIG. 7A. As illustrated in FIGS. 7A and 7B, the coil-beam structures 702 are arranged in an annular fashion to form a closed columnar structure 714. Weld strips 716 may be affixed to axial ends of each columnar structure 714 and flared outwards (i.e., bent outwards forming a substantially 90° angle) such that weld strips 716 may be coupled to the top sheet 704 and the bottom sheet 706 of the inflatable mattress 700.

FIG. 8 is a perspective view of an inflatable pool 800 incorporating another example of an implementation of the present disclosure. In this example, the tensioning structures 802 may include a plurality of I-beam structures 804, each having an open cell mesh construction, incorporated into the inflatable pool 800. The inflatable pool 800 may include a base sheet 806 with a circular edge and an inflatable hollow annular wall 808 coupled thereabout by, for example, sewing, stitching, heat or weld coupling. The wall 808 may comprise a hollow shell having an oval, circular, or rectangular shape or the like. There may be further provided a reinforcing ring-shaped inflatable base member 810 coupled to the bottom end of the wall 808. The base sheet 806, annular wall 808, and base member 810 may be constructed of a gas impervious, heat-sealable plastic material, such as PVC or other watertight and airtight material. The inflatable pool 800 may further incorporate other components not shown or described herein, such as water pumps, valves, piping, and motors known in the art.

FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 8. As shown both in FIGS. 8 and 9, the annular wall 808 may include an inner wall 812, an outer wall 814, and an interior annular cavity 816. The interior annular cavity 816 is defined by the spacing between the inner and outer sidewalls 812 and 814 when the pool 800 is inflated. The pool 800 may be inflated through one or more air valves (not shown) formed in one of the sidewalls 812, 814.

Ends of each I-beam structure 804 may be glued, welded, or otherwise adhered to the inner wall 812 and the outer wall 814 of the annular wall 808, respectively. The I-beam structures 804 may be coupled to the inner wall 812 and the outer wall 814 by an intermediate material, such as the weld strips (i.e., 204, 206, 502, and 716) described above, or other suitable means. The I-beam structures 804 may extend radially between the inner wall 812 and the outer wall 814 at spaced intervals of, for example, 15° to form a series of I-beam supports around the circumference of the interior annular cavity 816.

The open cell mesh construction of the I-beam structures 804 permits air admitted through the air valve to communicate with all points around the circumference of the annular cavity 816. In some implementations, the I-beam structures 804 may not extend to the top and/or bottom edges 818 and 820 of the annular wall 808 to provide an additional means for air admitted through the air valve to communicate with all points around the circumference of the annular cavity 816. The I-beam structures 804 provide increased support and strength to the inflated pool 800 so that water of substantial depths can be supported within the pool 800 before the sidewall 812 and 814 deform.

The open cell mesh construction of the tensioning structures of the present disclosure provide a weight savings over tensioning structures presently used in inflatable products that comprise solid pieces of material. The construction of the fibers comprising the mesh structure enables tension stresses to be distributed more effectively throughout the tensioning structure. Tensioning structures of the present disclosure are capable of withstanding high tension forces and are adapted to maintain the desired shape and structural integrity of the inflatable product even after surfaces of the inflatable product have been stretched beyond their elastic limit. Tensioning structures of the present disclosure are simple in structure, easy to manufacture, durable, and low in production cost. Tensioning structures of the present disclosure are, further, capable of withstanding high inflation pressure values; thus providing the support surface(s) of the product with an appropriate hardness to provide support and comfort to the user.

In general, terms such as “coupled to,” and “configured for coupling to,” and “secured to,” and “configured for securing to” and “in communication with” (for example, a first component is “coupled to” or “is configured for coupling to” or is “configured for securing to” or is “in communication with” a second component) are used herein to indicate a structural, functional, mechanical, electrical, signal, optical, magnetic, electromagnetic, ionic or fluidic relationship between two or more components or elements. As such, the fact that one component is said to be in communication with a second component is not intended to exclude the possibility that additional components may be present between, and/or operatively associated or engaged with, the first and second components.

The present disclosure may be used in any application where a lightweight, packable structure is needed to join two pieces of material that are urged away from one another in use. Although the previous description illustrates particular examples of various implementations, the present disclosure is not limited to the foregoing illustrative examples. A person skilled in the art is aware that the disclosure as defined by the appended claims and their equivalents can be applied in various further implementations and modifications. In particular, a combination of the various features of the described implementations is possible, as far as these features are not in contradiction with each other.
